slides(tappaas): correct the rewrite history, note the other instances

The ADR-007 rewrite was the move from a flat pile of sequenced scripts to the
manager/controller paradigm — not the dependsOn change. That was an earlier
and separate rewrite, ADR-003: a plain install.sh per module replaced by
dependsOn/provides contracts the platform resolves into an order.

Also: a closing line on the hardware slide that this is one of five known
instances, and the September 2025 gap now answers itself.
